MINING CAR.

Application filed April 19, 1921, Serial No. 462,632.

To all 719110770 it may concern.

Be it known that I. lVILLiAM Krnoinniiv, a citizen of the United States,and a resident of Van Buren, in the county of Crawford and State ofArkansas, have invented cer tain new and useful Improvements in MiningCars, of which the following is a specification.

This invention relates to a mining car, and particularly to thestructure thereof.

The object of the invention is to provide a car ofthe above characterwhich is made up of standard units and sections, said units and sectionsbeing adapted for casting or otherwise forming previous to theirassembly for forming the car.

It is also an object of the invention that the sections forming the bodyof the car be adapted for varying the width thereof.

Other object and objects relating to details of construction,combination and arrangement of parts will hereinafter appear in thedetailed description to follow.

The invention is illustrated by way of example in the accompanyingdrawings, in which- Figure 1 is a bottom plan view of an assembled carembodying my invention,

Figure 2 is a side elevation of the same,

Figure is an end elevation,

Figure 4 is a side elevation of an axle casting showing the stub shaftsfor journalling the car wheels, attached,

Figure 5 is a top plan view of an axle casting, the stub shafts forjournalling the wheels being removed,

Figure 6 is an end elevation of the axle casting as shown in Figure 4,and the stub shaft connected therewith being shown in cross section,

Figure 7 is a detail perspective view of a bumper.

Referring to the drawings more particularly A indicates a pair of endsections and B a pair of central sections. Each of the end sectionscomprise a bottom panel 10 and a pair of side panels ll, said panelsbeing secured together as shown. Also the end sections A are eachprovided with a pair of end panels 13 and 14 cut away as shown, toaccommodate the car wheels. Upon each adjacent edge of the panels 13 and14 there is bolted a strap 15, and between the straps 15 there issecured. a filler plate 16, said filler plate being adapted to permitthe width of Specification of Letters latent.

the car body to be increased when so desired. The middle sections B andend sections A. are secured to each other by the means of the straps 17,said straps being similar to the straps 15 andeach being formed with acentral rib 18 for strengthening the same. Also the straps 15 are eachformed with a rib 18 for a like purpose. The rear pair of end panels 13and 14 of the corresponding end section A are free from said section andsecured to a pair of arms 19 by the means of the straps indicated at 20.said arms being pivoted at their forward ends to the pins 21 whichproject from the side panels 12. As is obvious from this construction,the rear panels 13 .and 14 are free for vertical swingin movement.

For the axles of the car I provide a casting as shown in detail inFigures 4 and 5, said. casting consisting of two side portions 22 whichare integrally connected by the bridge or bottom 23, said bridge orbottom being preferably of the shape shown in Figure 4. Each of the sideportions 22 are formed with a series of lugs 24, and each of said lugsformed with a central opening adapted to receive a bolt by which saidaxles may be bolted to the bottom of the car body. At each. end of theaxle casting there is formed integrallytherewith a split sleeve 25, saidsleeve being adapted to receive the one end of a stub shaft 26. Each endof the sleeves 25 is formed with a pair of alined ears 27 through whichholes are provided for receiving the bolts 28, said bolts being adaptedto bring the divided edges of the split sleeves together for binding thestub shaft within said sleeve against removal.

Also it is preferable that the stub shaft have recesses as indicated at29 Figure 6, which register with recesses 30 (Figure 5) formed in thesplit sleeves 25. The bolts 28 extend within the recesses 30 and alsoengage in the recesses 29 and in this manner further hold the stubshafts 26 against displacement or removal. Upon each of the stub shafts26 there is formed a collar 31 which is adapted to limit the inwardmovement of the wheels 32 upon said stub shafts.

Upon each bottom panel 10 there is secured a bumper 33, said bumperconsisting of the casting as shown in detail in Figure 7 and having aplurality of openings 34 through which the bolts may extend for securingthe same to the bottom panels 10.

From the foregoing description it is thought that the advantages of thepresent invention can be clearly understood. It may be here pointed outthat should any unit of a car be broken, the same may be quicklyreplaced by substituting a unit of the same kind in stock. It may bealso here mentioned that the different sections and panels arepreferably secured together by means of- 2. An end section for a carbody of the class described, comprising a pair of side panels eachcarrying an end panel and the outer lower corner of each end. panelbeing cut away to accommodate the car wheels,

and a filler plate secured between the adjacent edges of the end panelswhereby the distance between said end panels may be increased ordecreased.

8. An end section for a car body of the class described, comprising apair of side panels, each carrying an end panel and the outer lowercorner of each end panel being cut aWay to accommodate the car wheels,at filler plate between the adjacent edges of said end panels adapted topermit the distance therebetween to be increased or decreased, and strapmeans adapted for securing said filler plate to the end panels of saidsection and also adapted to reinforce said filler plate.
